PIERON Torsion Springs – FAQ
A torsion spring is a mechanical spring made from coiled wire, designed to to store and transmit torque. It is commonly used in applications where a restoring force or controlled rotational movement is required. Torsion springs can be loaded in both closing and opening directions and are available in various shapes. These include, for example, leg springs and double leg springs.
The functioning of a torsion spring is based on the twisting of its wire. When loaded, the spring stores energy,, which is released again when unloaded. The spring’s legs transmit torque to adjacent components. At PIERON, we optimize this functionality through precise engineering, CNC-accurate coiling, and customized designs to ensure maximum performance across various load conditions and application profiles.
At PIERON, torsion springs are manufactured in several steps. PIERON uses high-quality materials such as spring steel, stainless steel, and special alloys, depending on the area of application and requirements for corrosion resistance or strength. CNC-controlled machines wind the wire with high precision, whereby different dimensions from very small to large wire diameters can be processedto meet a wide variety of customer requirements. Optimized heat processes reduce tension to guarantee durability and reliable restoring forces. PIERON offers various surface coatings, such as galvanizing, phosphating, powder coating, or custom paint finishes to increase corrosion resistance and wear resistance. Each spring is tested for functionality and quality to ensure compliance with the highest quality standards and to meet customer requirements.
In addition to standard solutions, PIERON also manufactures complex custom-designed solutions tailored precisely to specific customer requirements. These include, for example, torsion springs with variable coil diameters or combined leg configurations. State-of-the-art manufacturing techniques and rigorous quality control processes enable us to cover a wide range of wire diameters and a wide variety of spring diameters. This allows us to produce both very small, delicate torsion springs and robust industrial-grade solutions. The selection of high-quality and specialized materials, including corrosion-resistant stainless steels and advanced alloys, ensures reliable performance even in demanding environments. PIERON is committed to continuous research and development, combining traditional engineering expertise with modern technologies to deliver innovative solutions that meet the latest technical standards.
